Description

TECHNICAL FIELD

[0001] The utility model relates to the related field of gas quenching furnace small air door, especially to a gas quenching furnace small air door structure. BACKGROUND

[0002] The gas quenching furnace is a quenching equipment using high-pressure gas for cooling, and the commonly used cooling gas includes nitrogen and helium, etc. The gas quenching furnace will not cause pollution and discoloration on the surface of the workpiece during the quenching process. The gas quenching furnace cools the workpiece rapidly by high-pressure gas to achieve the purpose of strengthening the material. The gas quenching furnace usually adjusts the cooling air volume through a small air door to control the cooling speed of the workpiece during the quenching process. The greater the opening degree of the air door, the more air enters the cooling air chamber, and the faster the cooling air speed, and the cooling speed of the workpiece will also be accelerated accordingly. Conversely, the smaller the opening degree of the air door, the slower the cooling air speed, and the cooling speed of the workpiece will also be slowed down.

[0003] Most of the small air doors of the gas quenching furnace in the prior art have a single structure, and the control of the cooling air volume is realized by one or two air door plates that can be rotated. The stability and uniformity of the cooling air entering cannot be maintained, which leads to poor cooling effect. The air door plate that is frequently opened and closed also has the problem of poor sealing, which affects the subsequent use of the gas quenching furnace. The existing small air door does not have good independent disassembly capability, and it needs to be taken out as a whole from the gas quenching furnace door during maintenance, which is time-consuming and laborious.
